I am considering buying the new juicebox retrofit board to get myself started in the OpenEVSE world. I have exactly zero experience with OpenEVSE, and some experience with DIY electronics (ESP-home).

Could someone help me figure out, before I jump in:

* Is that board all-inclusive, or is any additional hardware required?

* Is it compatible with a screen, or at least a button?

* Is it pre-flashed, or do I need to get a programmer too? Which one?

Thanks in advance.

I have removed all timers and no solar divert, the MQTT is just to set the voltage value. I also get the No Ground fault but have checked all parts that need ground and all are valid.

When you change from start to manual mode faults are cleared.

As noted it has worked twice but now will not with no changes to the hardware setup.

Here is my status

Sorry to say after only 2 charges this board has now stopped working.

Seems to be stuck in "Starting" mode and will not detect the car.

I restarted via power off, waiting 5 min and starting the unit, I got the GFCI Error, then switched to manual mode and the error went away.  However, it will not go past the starting mode. Of note the 2 LEDs, flash red with the GFCI error, then purple then off.

I then tried the DEV firmware update to see if that would fix it, no luck.

Looking for suggestions, could I have a faulty board? 

I have attached my debug export.json file, do you need anything else?

Looking forward to getting this unit back in working order.

Thanks great support

Where on the board would this plugin, Can I use any other temp sensor? Can I suggest you add the extra add ons to the text of the shop page, I would have added them to the basket when I ordered the board. Shipping costs are a killer.  Your great board looked like it had all the bits on it ... :) 

Still have not worked out the "current" issue, so for now, it is way off, I have a question about the temp sendors, all my ones show zero on the web page, do I have to add them?

I am up and running, thanks :)  Questions... When plugged in the car is not charging but the dashboard shows 1.8amp 400w is charging. second question when it is charging it seems the current is above what is showing on the dashboard, so my guess is I need to update the calibration however can not find the spot to do this.  Again thanks for a great product.

@OpenEVSE Support - your website is expired - any plans on resolving that soon?  I had this bookmarked and was planning on purchasing the Juicebox kit today.

Allen Voshall, sorry I was wrong, as I had not turned on the board I did not see the 2 LED's next to the WiFi.  But would still like to add the extra LED's :)

Thanks ! This looks like a good idea, my replacement board however has no LED's on it so can not use this method. I plan on using the LED connector which has 3 LED's green, blue, and orange just need to know if the plug in LED's need to have a resistor added.

@Ernest DiNino I figured my situation out - even though I labeled each set of wires with a label maker, I somehow swapped the pair of wires for AC Input and AC Test wires. When I correctly wired them, the board turned on. Hope this helps!

@Ernest DiNino @David Tsao posting pictures of your installs (clear pics of all connections) would probably get useful responses. Also, the Discord server seems to be monitored more regularly: https://youtu.be/0MQJ4ZFYQyw

(We've swapped control boards in 25 Juiceboxes -- v0, v1, v2 -- and they're all working great)
